In case of passivation, the F-I/Os will switched into in the fail-safe state. After fault correction, the F-I/Os can be reintegrated. For the reintegration exists different possibilities and depends on wheter the F-I/Os support the RIOforFA-Safety PROFIsafe profile.

To prevent access to the hazard zone of a machine during operation, a protective door is installed and the position of the protective door is monitored. Since overrunning machine components may cause hazards, the protective door is interlocked and can only be opened after the machine is in standstill.

The ProjectGenerator can be used to quickly and easily create SIMOTION SCOUT (STEP 7 V5.x) projects. This includes SIMOTION CPUs, SINAMICS topologies, configuration and interconnection of technology objects and handling of software modules according to machine equipment modules. Also libraries and modules in existing projects can be updated.
